<P>PROBLEM TO BE SOLVED: To provide a circuit protective device 10 for restricting the damage to a circuit, due to the application of undesired voltage onto the circuit. <P>SOLUTION: A determining unit 25 determines whether voltages V3, V4 are applied to first and second conductive paths 23, 24 for applying a voltage to a driver IC21 and a control circuit 22. When it is determined by the determining unit 25 that the voltages V3, V4 are not applied to the first and second conductive paths 23, 24, first and second converters 13, 14 prevent output voltages V5, V6, V7, V8 from being applied to the driver IC 21 and the control circuit 22. <P>COPYRIGHT: (C)2007,JPO&INPIT |
